Abstract

The subject of the invention is a turbine for mixing a combustion mixture used for spark-ignition, internal-combustion engines and composed of air or air, fuel and exhaust gas.
The turbine as per the present invention consists of a body 1 with exhaust gas and air jets and an impeller mounted therein. formed from blades 3 and bars 4secured to hub and being radially spaced thereto. In the body 1 there are nozzles 5 and 6 for supply of air and exhaust gas. Blades 3 are bent on their periphery relative to their plane.

Description

  • The subject of this present invention is a turbine for mixing a combustion mixture used for spark--ignition, internal-combustion engines and consisting of air and fuel or air, fuel and exhaust gas. The process involves intimately mixing the components and atomising and evaporating fuel drops.
  • Components and assemblies of engine feed systems are known in the form of immovable and movable inserts whose aim is to atomise fuel drops and to facilitate evaporation along the way from the carburettor to the engine cylinders. These are generally inserts with holes and kerbs, ap- prppriately shaped profiles inserted into the stream of the mixture, or whirling components in the form of appropriately shaped impellers driven by the flowing mixture.
  • A turbine known from Polish Patent Application No. P-255,444 consists of a body and an impeller running in bearings and driven with the air and exhaust gas drawn in through the engine suction manifold.
  • The essence of the turbine consisting as per this present invention of a body with exhaust gas and air jets and an impeller rotatably mounted therein is that the body has an inner section increasing towards the flow of the mixture and the-impeller is consists of blades secured to a hub and bars radially spaced relative the hub, the blades being set at an angle varying from 10 to 20° relative the plane passing through the impeller rotation axis and perpendicular to the blade generatrix.
  • The body mounts jets for delivering air and exhaust gas at an angle varying from 30 to 70° relative the longitudinal axis of the impeller and preferably tangentially to the direction of rotation of the impeller blades. At thiir periphery from the side of the mixture inlet, the turbine blades are bent at an angle varying from 10 to 90° relative their plane.
  • The advantage of the turbine as per this present invention is that its construction enables. an appropriate mixture to be obtained, which is enchanced by a purposeful combination of blades and bars. The bars break fuel drops and make the mixture finer, whereas the final mixing and ho" mogenisation takes place when the mixture is passing between the impeller blades.
    Thanks to additional air being supplied to inside the turbine through an air jet in the turbine body, it is besides possible to again regulate the mixture composition and, when additionally delivering the exhaust gas, use is made of the effect of the gas-dynamic action of the exhaust jet on the mixture for further atomising it and the thermal energy of the exhaust gas for speeding up fuel evaporation in the mixture of air, fuel and exhaust gas so obtained.
  • The subject of this present invention is embodied in a drawing where Fig. 1 shows a cross section of the turbine, Fig. 2 shows a longitudinal sect- ion along line A-A, Fig. 3 shows a cross section along line B-B, Fig. 4 shows a longitudinal sect- ion through the exhaust gas delivering nozzle, Fig. 5 shows a side view of the blade.
  • Body 1 having an inner section increasing in the direction of the mixture flow has an impel- ler rotatably mounted therein and consisting of blades 3 and bars 4 secured to hub 2 and radially spaced relative the latter, blades 3 are set at an angle varying from 10 to 20° relative the plane passing through the impeller rotation axis and perpendicular to the generatrix of blade 3. Inside body 1 there are nozzles 5 and 6 for delivering air and exhaust gas at an angle varying from 30 to 70° relative the longitudinal axis of the impeller and preferably tangentially to the direction of the rotation of impeller blades 3. On the other hand, on their periphery from the side of the mixture inlet blades 3 are bent at an angle varying from 10 to 90° relative their plane.
